What should I dry 100% cotton on in the dryer.?
Answers:
Always start with the lowest temperature setting you have. It will prevent shrinking. Some dryers even have an "air dry" setting on the dials which allows the clothes to dry without using heat. If you don't have that option, start with the lowest setting. If that takes to long then go to the medium heat setting but check on the clothes often so that you can remove it from the dryer as soon as it is dry. That will help with the shrinking problem and the wrinkle problem. I never use high heat unless the clothing item is already preshrunk. I hope that works for you.
